Sick and tired of level switches failing!

not a answer to you question but I use a float that requires no power just gravity and its never failed me

If it where just ATO then yeah I could figure out a way to just do this mechanically. But its the automatic water change that really requires two switches, or a transmitter.

Doing a quick search on Ebay and reading some manuals seems like I can get a decent level sensor for $150 - $25 on Ebay. Think I'm going to pull the trigger on this one:



Made by flow line, it measures between 2" - 48" with a 3 mm accuracy. Should be good enough. Manual is here if any one is interested.

Are you running 120v through your switches ? This will cook them in short order
They're best used with low voltage
If you must use them on a 120v circuit, check out my thread on how to wire them through a relay

Wiring a float and relay to protect your ATO pump and more

One of the members posted this sensor link awhile back

For my ATO and AWC it's 24 VDC, I use 120 VAC for my SW mixing tank.

Hmm, that's odd about the dc ones
I've had a couple low-level switches in my sump for over a year and they are still working
I haven't even cleaned them yet

+1 to this, this is what I'm going to do on my new 120g
